Tip ? means hidden. The number shows how many piece identities are still possible.

Quick start

30 sec

Pick a piece; legal target squares light up.
After each move, impossible identities disappear.
Capture the final K candidate to win.

Rules

Every piece starts unknown.
Each move narrows what that piece can be.
Piece quotas are enforced globally.
Taking a K candidate removes that possibility.
